API

Receipts and board data.

The public board endpoint returns tracked markets, current calls, venue links, prices, probabilities, edges, and receipt fields.

The paid full verdict route is for one sealed market with reference notes and public receipt fields. It does not execute trades.

CALL means the market underprices this side. FADE means the market overprices this side. PASS means no real edge.
